Task 7 - Micro Combined Heat and Power

What is meant by 'heat-led'?

• 80% of the heat is used to produce heat to the property, whilst the power generation is secondary 15%.

• 50% of the heat is used to produce heat to the property, whilst the power generation is secondary 50%.

• 100% of the heat is used to produce heat to the property, whilst the power generation is secondary 0%.

• 30% of the heat is used to produce heat to the property, whilst the power generation is secondary 70%.

When will the unit produce electricity?

• When there is a demand for heat

• When there is a demand for cooling

• When there is a demand for water

• When there is a demand for gas

What are the four key components of a mCHP?

• The engine burner, The stirling engine generator, The supplementary burner, The heat exchanger

• The engine burner, The stirling engine generator, The supplementary burner, The water pump

• The engine burner, The stirling engine generator, The supplementary burner, The gas valve

• The engine burner, The stirling engine generator, The supplementary burner, The air filter

What are the location and building requirements for mCHP?

• The building should have high demand for space heating. The larger the building the greater the carbon savings.

• The building should have low demand for space heating. The smaller the building the greater the carbon savings.

• The building should have high demand for cooling. The larger the building the greater the carbon savings.

• The building should have low demand for cooling. The smaller the building the greater the carbon savings.

What is one reason a building with good insulation might not be suitable for mCHP?

• It has a high demand for space heating.

• It is likely to have a demand for space heating.

• It is unlikely to have a demand for space heating.

• It is dependent on weather conditions.

Which of the following is an advantage of installing mCHP?

• It increases the building's carbon footprint.

• It is dependent on building direction and weather conditions.

• It generates electricity only when there is no demand for heat.

• It saves carbon over centrally generated electricity.

What is a disadvantage of installing an mCHP system?

• The initial installation costs are low.

• It is suitable for all properties.

• It has limited capacity for electrical generation.

• It has unlimited capacity for electrical generation.
